Neuronal lipid droplets play a conserved and sex-biased role in maintaining whole-body energy homeostasis - Nature Metabolism In vivo regulation of neuronal lipid droplet formation mediates whole-body energy homeostasis in a sex-specific manner in Drosophila and mice.

Beyond delighted to share our amazing collaboration with Thierry Alquier's lab @alquierthierry.bsky.social on a conserved role for neuronal lipid droplets in regulating energy homeostasis in vivo led by Celena Cherian, Romane Manceau, Danie Majeur, and Colin Miller www.nature.com/articles/s42... /1

Updated preprint! Here, we identify an SREBP-dependent fatty acid sensing metabolic switch in Drosophila, enabling dramatic metabolic rewiring within adipose tissue that boosts carbohydrate metabolism in the absence of fat.

Lipid scrambling: New players, new questions, new opportunities Nearly a quarter of the proteins encoded in most organisms are transmembrane proteins. Contrary to textbook description, many feature a hydrophilic gr…

Amazing PhD @cristianrocharoa.bsky.social
and I have collected our thoughts and questions (many!) on lipid scramblases in this review:
www.sciencedirect.com/science/arti...
If you are interested in lipid transport and metabolism, membrane asymmetry and membrane protein function, give it a read!

Please share!!! I am looking for a postdoctoral researcher to join us. Focus will be on exciting collaborative projects on lipids and membrane biology, pushing the boundaries of in silico "reconstitutions". Previous experience with molecular dynamics simulations of biological systems a strong plus!

and Yoni! : )

It was so wonderful working with you on this! : )

Heterogeneity, dynamics and organelle interactions of lipid droplets - Nature Reviews Molecular Cell Biology Lipid droplets have key roles in energy storage and lipid metabolism. This Review discusses tools used for assessing lipid droplet heterogeneity, and how their heterogeneous composition and interactio...

With so many great reviews on LDs already out, do we need another?

Sarah @cohenlaboratory.bsky.social and I were approached by
@natrevmcb.nature.com to do a review on LD heterogeneity and inter-organelle contacts...topics in reviews, but not a focus. Fun project!

I've been waiting for this Titeca et al. story from Anne-Claude Gavin's lab to come out: A systematic, comprehensive analysis of lipid transfer protein cargo selection, a truly massive undertaking. What a time to work in lipid biology. Cool stuff every few days.

Membrane editing with proximity labeling reveals regulators of lipid homeostasis - Nature Chemical Biology Coupling an optogenetic lipid-modifying enzyme with proximity labeling reveals protein networks and mechanisms regulating lipid homeostasis in the membranes of target organelles.

Thrilled to share our latest study, led by @reikatei.bsky.social, in @natchembio.nature.com! We began by asking a simple question—how do cells know if they have too much of a lipid in a particular membrane, and how do they respond to rectify this imbalance?

ATG2A-mediated DAG transfer recruits DGAT2 for lipid droplet growth - Nature Structural & Molecular Biology Elhan et al. show that ATG2A acts with DGAT2, the enzyme producing triacylglycerol (TAG), in lipid droplet growth. By delivering diacylglycerol to lipid droplets, ATG2A not only fuels TAG production b...

Thrilled to share our latest work showing that the bridge lipid transport protein ATG2A transfers diacylglycerol (DAG), and some TAG/PA, from the ER to LDs, thereby recruiting DGAT2 to drive local TAG synthesis, promoting LD expansion while protecting ER membranes.

Lipid droplet growth is orchestrated by the seipin complex, which provides a structural platform for droplet nucleation and expansion. The microprotein adipogenin fine-tunes seipin’s conformation, remodeling its architecture to regulate lipid storage capacity. This modulation results in the formation of fewer but larger lipid droplets, revealing a key mechanism in lipid homeostasis.

Fat storage in the body relies on specialized structures called lipid droplets. In a new Science study, researchers identified the microprotein adipogenin as a regulator of adipocyte lipid droplet size, revealing a key mechanism in lipid homeostasis.

Adipogenin promotes the development of lipid droplets by binding a dodecameric seipin complex The microprotein adipogenin (Adig) is predominantly expressed in adipose tissues. Here, we found that Adig interacts with seipin to form a stable, rigid complex. We present the structure of the seipin...

New paper in Science identifying adipogenin as a critical seipin regulator in LD biogenesis. So glad our lab could help a little in this monumental study. Congrats to all authors!
